With the QR code, you can give instant access to websites directly. It doesn’t require you to type or remember a web address. You can use the Camera app to scan Quick Response (QR) codes for links to websites, apps, tickets, and more.

Types of QR Codes –

Quick response codes are a popular type of two-dimensional barcode. It encodes alphanumeric information. To decode it, you can use either a handheld scanner or even a scanning application on your smartphone.

QR codes vary in design and function, and mainly fall into one of the following categories – Static or Dynamic.

Static –

Static QR Code
  • The target data is encoded directly into the code, just as numeric data is encoded in a barcode.
  • The more information that is ‘densely’ encoded, the faster the response code will become.
  • The encoding is permanent, meaning that the target data can never be edited.
  • It is not possible to track scanning activity.

Dynamic –

Dynamic QR Code

A dynamic QR code is a better way to encode a URL into a QR code. This gives it more functionality and flexibility.

  • The target data can only be a URL.
  • The target URL is not stored directly in the quick response code. Instead, a shortened URL is encoded that redirects to the target URL.
  • It is possible to edit the encoded target URL at any time without having to reprint the square-barcode.
  • It is possible to track scanning activity and receive analysis.
  • You can ‘activate’ or ‘deactivate’ the code at any time.
